bug fix, the wrong setting at H5public.h causes library failed to be compiled on windows.
Description:
"long long" needs to be changed to long_long since "long long" can not be recongized on windows.
Solution:
Platforms tested:
MSVS 6.0 on windows XP
Linux 2.4 on heping
Misc. update:
Code cleanup
Description:
Clean up a few compiler warnings of various sorts...
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Bug fix
Description:
Correct bug where buffers that have only fractional elements (usually from
being compressed before being shuffled) would cause optimized algorithm to
dump core.
Solution:
Don't attempt to shuffle bytes unless we've got more than one element.

Bug fix.
Description:
The previous bug fix of H5Zscaleoffset filter was not secure enough.
Solution:
Slight modification based on previous version.
Platforms tested:
heping
Misc. update:
Purpose:
Bug fix
Description:
Some platforms (Windows) don't have the long long type, which causes automatic
Fortran type matching to fail.
A solution is to use HDF5's long_long type.
Solution:
Changed H5match_types.c to use long_long type. Moved definition
of long_long out of H5private.h and into H5public.h.
Platforms tested:
mir, copper, pommier
Bug fix
Description:
Kent reminded me that switching the logic wasn't enough, we really needed
to add the definition to the configure script.
Solution:
Do that.

Code cleanup
Description:
Switch name & logic from H5_LLONG_TO_FP_CAST_BROKEN to
H5_LLONG_TO_FP_CAST_WORKS, to better match the rest of the library.
Platforms tested:

Too minor to require h5committest
Bug fix.
Description:
The scaleoffset filter checks the uppper limmit of span of values
before it is assigned. The check for floating-point data, which may
not be represented in the machine exactly as the user wanted, did
not consider this.
Solution:
Slight modification of check above.
Platforms tested:
heping
Misc. update:
Bug fix
Description:
On visual studio 6.0, conversion from unsigned long long to double is not supported.
Even during compilation stage, it will fail.
Solution:
Albert changed the way the macro is handled so that for windowx MSVS 6.0,
the code that has conversion from unsigned long long to double will not compile.
Platforms tested:
windows, linux
Misc. update:
Add API calls allowing user control of the metadata cache.
Description:
Prior to this update, the metadata cache was not configurable
from outside the library.
Solution:
Add API calls allowing the user to configure the metadata cache
either at file open time, or for any open file. Also added calls
permitting the user to monitor cache size and hit rate. These
latter facilities are needed for "manual" cache size control

Misc. update:
Modifications.
Description:
Scaleoffset filter codes could not pass windows compiler.
Solution:
Modifications were made to make it pass. Also slight improvements of codes.
Platforms tested:

Misc. update:
Slight modification.
Description:
Several constants were added for the scaleoffset filter in
file H5Zpublic.h and corresponding changes needs to be made
in H5Zscaleoffset.c.
Solution:
Slight modification of codes.
Platforms tested:
heping, shanti
Misc. update:
New feature.
Description:
The scaleoffset filter has been implemented for compressing
floating-point data (float, double, but not long double)
using D-scaling method from GRIB. It also changes to
according to the new interface of H5Pset_scaleoffset API.
Solution:
Platforms tested:
heping, copper, shanti
Misc. update:
New feature.
Description:
The H5Pset_scaleoffset is changed for the scaleoffset filter
to handle both integer and floating-point data. Currently,
the D-scaling method from GRIB has been implemented for
compressing floating-point data.
Solution:
One more parameter is added to the H5Pset_scaleoffset interface
to let user specify what type of data is used and what method
to use as well as corresponding parameters.
Platforms tested:
heping
Misc. update:
Needs to update libtool's version number

Misc. update:
bug fix (sorta)
Description:
Rename H5_LLONG_TO_FP_CAST_WORKS to H5_LLONG_TO_FP_CAST_BROKEN
Solution:
Since a test for H5_LLONG_TO_FP_CAST_WORKS is not present in the configure script,
the dtransform test would assume that this cast doesn't work and skip the test. Change the variable around
so that, by default, it is assumed a long long to double cast does work.
Platforms tested:
minor change: copper, sol
Misc. update:
Bug fix
Description:
The intel compiler on windows doesn't support long long to double conversion.
Solution:
Added a flag H5_LLONG_TO_FP_CAST_WORKS. When it is not defined, the data transform will issue
an error when someone tries to perform a transform from long long to double and the long long to double
dtransform test will be skipped.
Platforms tested:
heping, sol, copper

Feature - libtool shared library versioning
Description:
Libtool provides a mechanism for different versions of the same shared
library to be distinguished. Now this is applied to HDF5 when it is
built as a shared library.
Solution:
The version number is stored in config/lt_vers.am, and included in
src/Makefile.am.
This number will be automatically updated by bin/h5vers; developers
only need to update it when they change the API.
*** IMPORTANT ***
Any time the API changes, the version number in config/lt_vers.am must
be updated!
Platforms tested:
mir, eirene, verbena, modi4
Misc. update:
Bug fix
Description:
Opening a dataset (or named datatype) with "." for the name and using a
group ID for the location ID was not returning an error value.
Solution:
Check the type of the object before attempting to open it (internally,
using a group ID and "." for the name maps to the group object).

Misc. update:
Description: When stream driver was not enabled, H5FD_STREAM variable
was not define. Fortran compilation failed since H5FD_STREAM
was needed to set up fortran global variables.
Solution: Followed MPIO driver model and defined H5FD_STREAM to be -1
when driver is not enabled.
Platforms tested: heping with --enable(disable)-stream-vfd
Misc. update:
New feature.
Description:
The scaleoffset filter previously does not use macros to handle
different integer datatype situations.
Solution:
Added macros in the filter for better maintenance and clarity of codes.
Platforms tested:
heping, copper, shanti
Misc. update:
Minor feature
Description:
If a user configures without C++ or Fortran, 'make' will not recurse into
c++ or fortran directories. However, if the user cd's into these
directories and 'makes,' the Makefiles will attempt to build interfaces
that have not been configured, usually failing.
In an unrelated but minor change, src/H5detect should be compiled with
the -g flag to disable compiler optimizations since it is only
executed once.
Solution:
Make it harder for users to try to compile interfaces that have not been
configured by making c++, fortran, and hl directories not recurse into
their subdirectories unless they have been configured.
Thus, 'make' in /fortran/src will break if Fortran has not been configured,
but 'make' in /fortran will not break.
Platforms tested:

Description: Removed support for SRB driver
Solution: Removed or modified appropriate files; ran reconfigure
to regenerate Makefile.in and configure files.

Misc. update: ran bin/chkmanifest on heping
Bug fix.
Description:
The current HDF5 library call H5Tget_size when called by the filter
does not give the correct disk size for varible-length and variable-length
string. The filter needs to have another way, if possible, to get their
sizes.
Solution:
The filter can only solve this problem if varible-length and variable-length
string is a member of compound datatype. The filter does not support the
situation where an array datatype has variable-length or variable-length
string as its base datatype.
Platforms tested:
heping, shanti
Misc. update:
Activating collective IO supports for irregular selction inside HDF5 dataset.
This support doesn't include to build the final complicated MPI derived datatype support for chunking storage.
Description:
Support collective chunk IO for both contiguous and chunking storage for irregular selection( using H5S_SELECT_OR for multiple hyperslab selection)
Solution:
Using MPI derived datatype to realize this feature.
Problems still need to be investigated:
Big size irregular hyperslab selection test may cause MPI hang or abnormalexit with MPICH family on various platforms. This is really hard to debug since sometimes it can work and sometimes it cannot work. We will continue investigating those cases. This may not be parallel HDF5 bugs since with the recent version of poe at IBM platforms, all tests passed.
Platforms tested:
1. Linux heping 2.4.21-27.0.1 with mpich
2. AIX 5.1 copper with mpcc_r
3. Altix cobalt SGI linux 2.4.21-sgi304rp05031014_10149 with icc -lmpi
4. Linux Cluster SDSC TG, intel 8-r2 with mpich 1.2.5
5. NCSA Linux Cluster Tungsten, MPICH-TCP-1.2.5.2, Intel 8.0 under lustre
6. NCSA Linux Cluster Tungsten, MPICH-LAM-INTEL711, sometimes not working
7. NCSA Linux CLuster Tungsten, champion-pro-1.2.0-3, not working for other collective IO tests, but work for irregular selection collective IO test.
Misc. update:
Description: Split test/dtypes.c because it's so big. Moved all integer-integer,
floating-floating, integer-floating, floating-integer, derived integer, derived
floating conversion tests to a new test program, dt_atomic.c. The test remains
the same basically.
Platforms tested: fuss and h5committest
Misc. update: MANIFEST
Configuration feature
Description:
Different Fortran compilers mangle function names in different ways
(upper case, lower case, adding underscores). To link between
Fortran and C functions, we need to know what a given function's
name is under a given compiler.
Solution:
Use autoconf's FC_WRAPPERS check to determine the Fortran
naming scheme and define the FC_FUNC_ macro to name our
functions (in H5f90proto.h). Removed references to
our old FNAME macro, as well as flags that indicated whether
function names were upper or lower case.

Bug fix
Description:
On some machines, $RUNSERIAL variable needs to be used to run
tests. Set $RUNTESTS (which is used for non-parallel tests) to
be $RUNSERIAL in configure.am.
Also, since I was updating all Makefiles.in anyway, I updated
commence.am to point to autotools installs in AFS instead of
those on heping.
Platforms tested:
mir, sleipnir, modi4, copper
Purpose:
"Bug fix"
Description:
Hardcoded Makefiles to use /bin/sh instead of letting configure
detect shell automatically. This is what v1.6 does, and avoids
problems on janus.

Feature - conditional compilation
Description:
SRB file driver and tests are now compiled only when SRB is enabled
(using --with-srb during configure).
Solution:
Added an automake conditional in configure.in, altered Makefiles.am in
src and test directories to depend on that conditional.
This should make a nice example for posterity to add conditionally
compiled sources.
Platforms tested:
heping (only configure change)
Description: During last change, part of the code wasn't updated in
copy and paste accordingly. It was in the exception handling of NaN
in H5T_conv_f_f().
Solution: Corrected.
Platforms tested: No test needed - trivial.
